Hair Loss Panel

A targeted panel investigating the most common metabolic and hormonal causes of hair loss through 12 biomarkers: TSH, ferritin, zinc, selenium, vitamin B12, folic acid, LH, FSH, DHEA-S, estradiol, testosterone, and a blood count. Covers thyroid dysfunction, iron deficiency, nutritional gaps, and hormonal imbalances — the treatable factors behind the majority of non-genetic hair thinning.

Hair loss has numerous potential causes, but blood testing can efficiently identify or exclude the most common treatable contributors. Iron deficiency measured via ferritin is one of the most frequent factors in diffuse hair loss, particularly among women. Hair follicles are highly sensitive to ferritin levels, and thinning often begins well above the clinical anaemia threshold where standard screening would flag a problem. Thyroid dysfunction via TSH affects hair growth in both hypothyroid and hyperthyroid states. Zinc and selenium deficiency impairs the hair follicle growth cycle and keratin production. Vitamin B12 and folic acid are required for the rapid cell division that hair growth demands. The hormonal markers assess androgenetic patterns: elevated testosterone or DHEA-S may indicate androgen-driven thinning, and the FSH-to-LH ratio can reveal hormonal imbalances associated with conditions like PCOS that frequently present with hair changes. Estradiol provides context for the broader hormonal environment. The blood count screens for anaemia, which directly reduces oxygen delivery to hair follicles. These 12 markers provide a systematic workup of the most common reversible causes, directing treatment at actual deficiencies rather than empirical supplementation. Results are typically available the same day at the Munich laboratory.
